The WoodChuck Combination Chisel Wood-Rasp from Cooper Tools® is a three-piece set that includes a 1/2-inch, 3/4-inch and 1-inch combination tool. Each can act as a chisel, a flat rasp and a round rasp. The steel strike plate on the handle resists mushrooming and breaking. The polished and ground blades are extremely sharp for crisp cuts. The flat wood rasp is used for rapid stock removal. The half-round wood rasp is used to enlarge round surfaces.
